Baruch Spinoza

The greatest pride, or the greatest despondency, is the greatest ignorance of one's self.

Blessedness is not the reward of virtue but virtue itself.

Do not weep; do not wax indignant. Understand.

Freedom is absolutely necessary for the progress in science and the liberal arts.

Those who are believed to be most abject and humble are usually most ambitious and envious.

One and the same thing can at the same time be good, bad, and indifferent, e.g., music is good to the melancholy, bad to those who mourn, and neither good nor bad to the deaf.

Whatsoever is contrary to nature is contrary to reason, and whatsoever is contrary to reason is absurd.

The world would be happier if men had the same capacity to be silent that they have to speak.

Peace is not the absence of war, but a virtue based on strength of character.

Desire is the essence of a man.

If men were born free, they would, so long as they remained free, form no conception of good and evil.

So long as a man imagines that he cannot do this or that, so long as he is determined not to do it; and consequently so long as it is impossible to him that he should do it.

Will and intellect are one and the same thing.

Only that thing is free which exists by the necessities of its own nature, and is determined in its actions by itself alone.

I call him free who is led solely by reason.

Nothing exists from whose nature some effect does not follow.

Fear cannot be without hope nor hope without fear.

There is no hope unmingled with fear, and no fear unmingled with hope.

None are more taken in by flattery than the proud, who wish to be the first and are not.

Ambition is the immoderate desire for power.

We feel and know that we are eternal.

It may easily come to pass that a vain man may become proud and imagine himself pleasing to all when he is in reality a universal nuisance.

I would warn you that I do not attribute to nature either beauty or deformity, order or confusion. Only in relation to our imagination can things be called beautiful or ugly, well-ordered or confused.

All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.

Peace is not an absence of war, it is a virtue, a state of mind, a disposition for benevolence, confidence, justice.

If you want the present to be different from the past, study the past.

All things excellent are as difficult as they are rare.

He alone is free who lives with free consent under the entire guidance of reason.

Nothing in the universe is contingent, but all things are conditioned to exist and operate in a particular manner by the necessity of the divine nature.

God is the indwelling and not the transient cause of all things.

Desire is the very essence of man.

To give aid to every poor man is far beyond the reach and power of every man. Care of the poor is incumbent on society as a whole.

True virtue is life under the direction of reason.

Fame has also this great drawback, that if we pursue it, we must direct our lives so as to please the fancy of men.

Self-complacency is pleasure accompanied by the idea of oneself as cause.

The endeavor to understand is the first and only basis of virtue.

Whatsoever is, is in God, and without God nothing can be, or be conceived.

For peace is not mere absence of war, but is a virtue that springs from, a state of mind, a disposition for benevolence, confidence, justice.

I do not know how to teach philosophy without becoming a disturber of established religion.

Be not astonished at new ideas; for it is well known to you that a thing does not therefore cease to be true because it is not accepted by many.

The highest activity a human being can attain is learning for understanding, because to understand is to be free.

Men govern nothing with more difficulty than their tongues, and can moderate their desires more than their words.

Sin cannot be conceived in a natural state, but only in a civil state, where it is decreed by common consent what is good or bad.

Pride is pleasure arising from a man's thinking too highly of himself.
